Verified by Toppr

The number of taxa present within a particular area or an ecosystem is called alpha diversity. It is also the diversity present within the community. The term was introduced by R. H. Whittaker. Example of such diversity includes high tree diversity throughout the Amazon Rainforests of Ecuador. Generally, gamma diversity = alpha diversity x beta diversity.
So, the correct answer is 'α - diversity'.
